This pistol, likely of Afghan origin, bearing many similarities to higher end of the Khyber Pass firearms is a rare beast. Due to the workmanship of the lock I believe this is a British trade lock that has had a spurious EIC Lion engraved in to increase its value or make it seem more attractive to a contemporary buyer.
The pistol has a Damascus barrel that has been inlaid with silver and engraved with an approximation of c1800 British arabesque designs.
The action is in good condition, there is minor wear to the silver.
This pistol can be yours for £795 or best offer.
